Prevention is always better than cure, this saying perfectly fits to our concept of Oral hygiene, What i mean to say is that in dentistry the time matters, if we neglect the disorders of our oral health may lead to major mishappens regarding our precious health. So be aware and start looking for good aids and tips to maintain the oral hygiene.
The first basic thing in maintaining the good oral hygiene is toothbrushing, start at the right time and with proper tools, i think no one needs a introduction to a thing like tooth brush.And upon that thanks to the techno world who has introduced a ELECTRIC TOOTHBRUSH.
It has seen that electric toothbrush has more advantages than manual toothbrush.
==> Most of us do hurry while brushing with the manual toothbrush instead of the recommended time.
==> But in electric toothbrush one individual will spend at least two minutes of toothbrushing.
==> Secondly the power brushes put the same movement throughout the brushing with the consistent pressure levels. This assures that it will make less wear and tear of the tooth structure and less gum irritation.
==> Many times there is excessive wear in certain areas due to maloclussion and and certain systemic disorders where the more wear and tear of this certain areas is controlled with the electric toothbrush.
==> Laboratory studies have also came to conclusion that those using Electric toothbrush shows reduced levels of plaque colonies than those using the manual toothbrush.
==> Regarding the safety, electric toothbrush are safe and gentle as a manual toothbrush, because there are certain brands which has pressure sensors , automatically stops the toothbrush if too much of pressure is applied.
==> About comfort, Electric toothbrushes have ergonomic handle with non-slip controll grips ensures optimum comfort and maneuverability.
==> About speed, various brands in the market available vary from each other with the press of a button, you can chose between two speed settings according to your preferences.
==> As the time span of brushing is important there are timers to the electric toothbrush, Memory timer tracks brushing to help ensure the recommended two minutes of brushing is accomplished even if brushing is briefly interrupted.
==> Electric tooth are clinically proven to clean better than a manual toothbrush, improve health of gums , Prevent build up stains and be gentle with the gums as a soft manual toothbrush.
The importance of good brushing lies in the prevention of dental caries and tooth decay. Whether manual or electric proper movement of the brush over the teeth is very important. Brushing teeth regularly twice a day maintains good oral hygiene.

Above all it helps to preserve the aesthethic quality of the teeth and that big "close-up " smile and the overall health of an individual. It helps to keep our self-esteem high.

tooth


Tooth One of the structures found in the mouth of most vertebrates which, in their most primitive form, were conical and were usually used for seizing, cutting up, or chewing food, or for all three of these purposes. The basic tissues that make up the vertebrate tooth are enamel, dentin, cementum, and pulp (see illustration).


Structure of a tooth.
Enamel is the hardest tissue in the body because of the very high concentration, about 96%, of mineral salts. The remaining 4% is water and organic matter. The enamel has no nerve supply, although it is nourished to a very slight degree from the dentin it surrounds. The fine, microscopic hexagonal rods (prisms) of apatite which make up the enamel are held together by a cementing substance.
Dentin, a very bonelike tissue, makes up the bulk of a tooth, consisting of 70% of such inorganic material as calcium and phosphorus, and 30% of water and organic matter, principally collagen. The rich nerve supply makes dentin a highly sensitive tissue; this sensitivity serves no obvious physiological function.
Cement is a calcified tissue, a type of modified bone less hard than dentin, which fastens the roots of teeth to the alveolus, the bony socket into which the tooth is implanted. A miscellaneous tissue, consisting of nerves, fibrous tissue, lymph, and blood vessels, known as the pulp, occupies the cavity of the tooth surrounded by dentin.
The dentition of therian mammals, at least primitively, consists of four different kinds of teeth. The incisors (I) are usually used for nipping and grasping; the canines (C) serve for stabbing or piercing; the premolars (Pm) grasp, slice, or function as additional molars; and the molars (M) do the chewing, cutting, and grinding of the food. Primitively the placentals have 40 teeth and the marsupials 50.
In therian mammals, probably because of the intricacies and vital importance of tooth occlusion, only part of the first (or “milk”) dentition is replaced. This second, or permanent, dentition is made up of incisors, canines, and premolars; as a rule only one premolar is replaced in marsupials. Although the molars erupt late in development and are permanent, that is, no
